GEORGE V. ANDERSON, OF WILMINGTON, DELAWVARE, ASSIGNOR OF SEVEN- SIXTEENTHS TO CHARLES XV. GOUERT, OF SAME PLACE.

MACHINE FOR STAKING AND SOFTENING SKINS.

SPECIFICATION forming part of Letters Patent No. 391,221, dated October 16, 188.

Application filed June 27, 1888. Serial No. 278,337.

To aZZ whom it may concern.-

Be it known that I, Gnonon V. ANDERSON, a citizen of the United States, residing at WVilmington, in the county of New Castle and State of Delaware, have invented a new and useful Improvement in Machines for Staking and Softening Skins, which improvement is fully set forth in the following specification and accompanying drawings.

My invention relates to the class of machines adapted for staking and softening skins as embodied in the Letters PatentNo. 380, 239, granted on the 27th day of March, 1888.

The invention consists of means, substantially as hereinafter set forth and particularly claimed, whereby the machine is of reduced height, more compact, simplified, and of increased effectiveness.

Figure 1 represents a partial side elevation and partial vertical section of a machine for staking and softening skins embodying my invention. Fig. 2 represents a partial top view and partial horizontal section of a detached portion thereof. .Fig. 3 represents a section of a portion on line m, Fig. 1.

Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings, A represents the frame of the machine, and B the drivingshaft mounted thereon,saidshaft carryinga sprocket-wheel, B.

O D represent parallel countershafts, which are mounted on the upper portion of the frame A, the shaft 0 carrying a pinion,E,and sprocket-wheel F. Passing around the sprocketwheels B F is an endless chain, G, whereby the power of the shaft 13 may be transmitted to the shaft 0. The shaft D carries a spurwheel, H, and cam J, said wheel H meshing with the pinion E, whereby power is communicated to said shaft D. The cam J is formed with a horizontally-projecting rim or flange, as shown in Fig. 1.

K represents a rising and falling beam, which is vertically arranged and guided on the frame A and connected with the same by means of links K and bellerank or elbow levers L, which are mounted on brackets or Connected with the elbow-levers are links N, which are pivoted to a beam, P, which is vertically ar- (No model.)

ranged and receives horizontal motions, due to the action of the links N K, elbow-levers L, and bcamK,the latter having atits upper end rollers Q, which engage with the rim of the the frame A, whereby the beam is guided in its motions. The upper end of the beam is connected with a sliding frame, S, which is guided horizontally on the frame A and carries a head, T, opposite to which latter is a bed, U, supported on the frame, said head and bed constituting a clamp by which the skins are held during the staking action. The faces of the head and bed are V-shaped or angular and clad with rubber or other suitable elastic or flexible material, whereby their holdingpower is increased.

The frame S consists of side rods, S, and end bars, S S The bar S" is loosely fitted on the rods S and bears against spiral springs S encircling said rods, the latter carrying nuts a, whereby the location of the bar S and tension of the springs S may be adjusted. The bar S also carries a bearing-piece, S for the upper end of the beam P,whereby as the beam advances the frameis also advanced, so that the headTis forced against the bed U, the springs S compensating for any irregularity in the skins between the clamp and preventing injury to the parts thereof, due to any excessive strain that may be occasioned.

The lower end of the beam P has :llttcd on it avertical slide,V, to which is attached a horizontally arranged movable cross head, W, which is mounted on a rising and falling carriage, X, the latter being guided on the uprights of the frame A and receiving motion from a rod, Y, which is attached to said carriage and to a crank-wheel, Z, the latter being keyed or otherwise secured to the countershaft D.

The slide V is connected with the crosshead W by means of a horizontally-arranged bolt,V,which is secured to said slide and enters an eye, W, rising from the cross-head, said bolt carrying suitable nuts, b, whereby the connection of the slide and crosshead may be adjusted. The end of the cross-head opposite to the slide has secured to it an arm, W whose upper end carries the knife A.

Rising from the carriage X is a standard, X, on which is mounted a swinging arm, X whose upper end carries the pad 13, and whose lower end is connected by a link, X, with the cross-head WV, it being seen that as the cross-head is moved the knife A and pad B are caused to approach and separate, as the case may be, said parts projecting toward each other, so as to act upon the skin when advanced toward each other to full extent.

It will be noticed that as the carriage X is raised or lowered the cross-head W, the knife and pad A B, and the slide V are carried by the same, said slide V moving up and down on the side of the beam P as thelatter advances and recedes.

The operation is as follows: Power is communicated to the shaft B, whereby the parts of the machine are set in motion. A skin is placed adjacent to the face of the bed U and the head T advances toward the same. The carriage X also rises, and when it is at its highest point the beam P has advanced to its full extent, whereby the head T presses the skin against the bed U and firmly clamps the same. The knife and pad now close against the opposite side of the skin, after which the carriage begins its descent, and the knife and pad,following the same act upon the skin, perform the staking and softening operation. When the carriage has completed its descent, the crosshead W is drawn back by the returning beam P. The arm W of the knife A fol lows said cross-head, and, owing to the link X and arm X the pad B is swung outwardly, whereby the knife and pad are separated simultaneously. The head T recedes, whereby the clamp is opened and the skin released. The skin may now be turned or shifted and then returned to the bed, so that as the maehipe continues its operation the carriage rises and the head advances, so that the skin is again held, the knife and pad also closing, so that the skin is further staked or acted upon, the operation being continued as long asdesired.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a machine for staking and softening skins, the clamp and knife-moving beam P, connected with operating mechanism consisting of elbow-levers pivoted to said beam and the frame of the machine, and another beam, K, connected with said levers, and a rotary cam engaging and imparting a rising and falling mot-ion to said beam K, said parts being combined substantially as described.

2. In a machine for staking and softening skins, a frame with driving-shaft journaled therein, ashaft carrying a cam and connected with and operated by the driving-shaft, avertieal rising and falling beam operated by the rotation of said cam, a vertical beam connected to said rising and falling beam by a belllever, and links adapted to move horizontally, and aknife and pad connected with and adapted to move with said horizontally-moving beam, said parts being combined substantially as described.

3. In a machine for staking and softening skins, a frame with driving shaft, a cam operated by rotation of said shaft, a rising and falling beam actuated by rotation of said cam, a vertical beam connected by links and levers to said rising and falling beam and adapted to move horizontally, a vertical slide on said horizontally-moving beam, a cross-head connected to said slide and having an arm with knife, and a swinging arm having a pad and linked to said cross-head, said parts being combined substantially as described.

4. A machine for staking and softening skins, consisting of a driving-shaft, countershafts with a pinion spur-wheel, cam, and crank-wheel, respectively, thereon, sprocketwheels on the driving-shaft and one of the counter-shafts, and an endless chain on said wheels, a rising and falling beam, an advancing and returning beam, elbow-levers connected with said beams, a slide fitted on the second-named beam, a cross-head attached to said slide, a rising and falling carriage support-ing said cross'head, a' rod connected with the aforenamed crank-wheel and said carriage, a knife attached to the cross-head, and a pad havingits supporting-arm mounted on a standard on the carriage and connected by a link with said cross-head, the parts enumerated being combined substantially as described.

5. The combination of a frame, a horizontally-moving beam with a vertically-moving slide thereon, a cross-head connected to said slide having an arm with knife, a standard secured to the frame, and aswinging arm pivoted to the standard and having a pad at its upper end and linked at its lower end to the crosshead, substantially as and for the purpose set forth.

6. In a machine substantially as described, the carriage X, the cross-head W, the slide V, and beam 1?, in combination with the bolt V and eye WV, which connects said head and slide, substantially as described.
